Canopy cover mapping
Canopy cover is a necessary criterion for calculating the area of the leaf surface per 1 ha of forest covered area. It is determined through the area of canopy per 1 ha of forest. The initial basis for calculations was a mosaic basemap of space images of ArcGIS Imagery, spatial resolution of which allows us to visually detect the presence of vegetation and forest areas selected on the Sentinel image. Canopy cover mapping was performed with the use of licensed software package ArcGIS 10.4. In order to estimate canopy cover, the extent of the studied area was divided into grid squares of 100m*100m. Then, overlay operations were performed for each square using GIS-technologies to calculate the area occupied by vegetation. The result of measurements obtained by the grid square method is shown in the figure (Fig. 7).
